| Abstract: | With the features of observing large area synchronously, temporally, and economically, remote sensing technology provides the possibility for dynamic monitoring soil moisture of large area. The development and application of the remote - sensing technology in monitoring soil moisture was reviewed, and the application of vegetation index method in arid regions which based on visible and thermal infrared bands was introduced in this paper. It also analyzed advantages and disadvantages of various remote- sensing methods in monitoring soil moisture, pointed out shortages of the remote - sensing methods, prospects of the technology of using remote- sensing to monitor soil moisture monitoring. |
